Abstract

L'invention concerne un élément bipolaire destiné à être assemblé de manière à former un électrolyseur à filtre-presse pour l'électrolyse de l'acide chlorhydrique au moyen d'un cathode à oxygène dépolarisée, constituée par une feuille simple en titane ou alliages de titane, munie d'un joint à sa périphérie. Des saillies oblongues, orientées verticalement dans le sens de leur plus grande longueur, sont obtenues par pressage dans la feuille simple. Les saillies s'étendent alternativement sur les deux faces de la feuille. Les saillies sur une face de la feuille peuvent être identiques ou de dimensions différentes par rapport à celles de l'autre face et sont, de préférence, caractérisées par une section triangulaire dont l'angle aigu au sommet représente la partie la plus importante. Le sommet est arrondi pour éviter des ruptures du matériau lors du formage et est, de toute façon, exempt de surfaces planes appréciables en vue d'éviter la formation d'aires masquées lorsque les électrodes sont fixées sur les saillies sur les deux faces de la feuille simple.
